There was no calming him down at this point, the closest they could hope for was immobilizing him entirely or knocking him out. He didoesn't stop struggling, if anything it only got worse when one of them moved between him and the way out. He was frightened and completely panicked, and it showed in his voice when he yelled, "Let me go!"

He still didn't know who these people were, but they they were holding him down and in his mind that made them as much of a threat as the doctor and Cinder.
